  • Transdermal administration of pharmacologically active amines using hydroxide-releasing agents as permeation enhancers
    Patent number: 6719997
    Abstract: Methods, compositions and drug delivery systems are provided for the transdermal administration of a pharmacologically active amine. The active agent is administered with a hydroxide-releasing agent that serves as a permeation enhancer. Exemplary hydroxide-releasing agents are inorganic hydroxides, inorganic oxides, and alkali metal or alkaline earth metal salts of weak acids. Inorganic hydroxides include, for example, ammonium hydroxide, alkali metal hydroxides and alkaline earth metal hydroxides, such as sodium hydroxide, calcium hydroxide, potassium hydroxide, magnesium hydroxide, and the like.

  • Transdermal administration of phenylpropanolamine
    Patent number: 6602912
    Abstract: Methods and systems are provided for the transdermal administration of racemic phenylpropanolamine, i.e., a mixture of two or more of the four isomers of phenylpropanolamine, (+)-norephedrine, (−)-norephedrine, (+)-norpseudoephedrine, and (−)-norpseudoephedrine. Generally, the racemate will be a mixture of (+)-norephedrine and (−)-norephedrine. The racemic drug is administered along with a permeation enhancer. The permeation enhancer is preferably a basic compound, and optimally is a hydroxide-releasing agent such as sodium hydroxide.
